Thank you for your response...
We run multiple servers for our application.
We have a configuration as follows:
1. Portal ... running tomcat 7.0_45 and java 7... this is the outward
facing running jetspeed. This is the server throwing the errors
2. Tomcat ... running tomcat 7.0_45 and java 7... this is our back-end
business logic server
3. Mule .. enterprise service bus broker ... no tomcat running java 7
4. AiM .. our ERP software from a third party ... runing tomcat_9 and
java 11
We cannot upgrade Java at this point, because of an old third party application
running on the portal. It requires Java 7.
We are currently exploring new packages to replace it, but this will take some
time to finalize.
I've attached the catalina log showing the error. The error appears on startup
of Tomcat.
I tried to replace the annotation_api.jar with a newer version, somewhere on
the web, it was posted that replacing this jar file with a new version solved
his problem; which was simular to mine.

You'll need at least 7.0.88 for Java 11 support.

That is what I would recommend (or latest 8.5.x / 9.0.x but that is probably
changing too much in one go).

You are going to have to try this again. Can I suggest you post the first error
you see here and we can try and talk you through fixing it.

Why do that?
